Can You imagine how will this engine/heli sound in flight?

DNHP use it in his BIG200 industrial heli with 215cm3


Sure the pilot needs also BIG balls to fly this monster, and I think I´ve found the pilot. One with very very big balls.

Yes, that is exactly what it is. It has a push button starter.

Looks like a car starter.. that thing pops up to engage the engine then retract when engine started. Pretty cool!

It's an industrial helicopter for heavy payload.. not for average helicopter enthusiast.. You're looking at least $25,000 USD ..

US$25,000 - that's a relief, for a minute there I thought it was going to be expensive!

25000 usd plus all radio equipment, I´m lucky to have some spare futaba S3001 servos. May be using five of them on each channel it will work right.

Yes they start at around 18K for the kit. If you want the Yamaha version add another 80K.

Here is a link for the web site. http://www.dnhp.co.kr/BIG/BIG.htm

This little hawk flew into the hanger about about five months ago, and guess where he landed. This little guy is quite at home around these larger machines and I do bleieve that he would take both the cat and the squirrel.

Damn canopy reminds me of the look of this toy helicopter

Linear actuator? must be having lots of torque in it

With 80Lbs of crushing force you wouldn't want to get your hand caught in one of these "Servos"

I don't know anything about the above mentioned craft, but the RMAX uses three of these little jewels.

Look closely, what you believe to be the fourth servo is actually an a arm. (see grey a arm on right side.)

840-850 main rotor rpm, if my memory is correct.

Ok I thought it was a 4 servo 90º CCPM.. The 4th arm kind of an anti-rotation arm ..
